Polyglycol is a polyether polyol derived from ethylene oxide. It is a colorless, viscous liquid with a mild odor and is used in a variety of industries, including cleaning agents and lubricants. Common applications for polyglycol include surfactants, emulsifiers, and dispersants.
Common types of failures when rubber is exposed to polyglycol include softening, swelling, cracking, and disintegration. The polyglycol molecules interact with the rubber molecules, causing the rubber to swell and become softer. Over time, the rubber may become brittle and start to crack and disintegrate. Additionally, the polyglycol molecules can also leach into the rubber, reducing its flexibility and weakening its performance.
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
